Problems solved by technology

Therefore, temperature is the key factor affecting the plastic deformation ability of magnesium alloys. The plastic forming temperature range of magnesium alloys is relatively narrow, generally in the range of 300-450°C. When the forming temperature is low, the deformation ability of magnesium alloys is poor, and it is easy to produce cold. Cracks, when the temperature is too high, some low-melting point phases in the alloy may melt during the forming process, and thermal cracks are prone to occur under the action of stress. In addition, if the forming temperature is too high, the grains of the microstructure of the part will also be coarse. Directly affect the service performance of materials
